UCC2751D

Telecom Overview

The UCC2751D is a dual-channel high-speed MOSFET gate driver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 18 V and delivers peak output currents of 3 A source and 6 A sink per channel. The device utilizes a SOIC-16 package with a width of 0.295 inches (7.50 mm). Key timing parameters include a maximum propagation delay of 25 ns and rise/fall times of 15 ns. It supports input logic levels compatible with TTL and CMOS standards, functioning effectively across an operating temperature range from -40°C to +85°C.

Telecom Feature Summary

• Dual-channel configuration providing independent control for high-side and low-side switching applications
• High-speed performance characterized by fast propagation delays and symmetric rise and fall times
• Robust input structure designed to tolerate negative transient voltages without damage

Telecom Applications

• Synchronous rectification in DC/DC converters
• Half-bridge and full-bridge power stage driving
• Motor control systems requiring precise gate drive signals

Telecom Procurement Notes

Verify the current marketing status before design implementation. The UCC2751D is classified as Not Recommended for New Designs (NRND) according to official documentation. Engineers should confirm availability through authorized distributors and evaluate alternative components for new product development cycles to ensure long-term supply stability.

Telecom Selection Notes

Select this component when a dual-channel driver with asymmetric current capabilities is required. The 6 A sink current facilitates rapid turn-off of power MOSFETs, while the 3 A source current ensures adequate turn-on speed. Ensure the application environment remains within the specified -40°C to +85°C temperature range and that the supply voltage does not exceed 18 V.

Telecom Part Context

This part belongs to the UCC2751x family of high-speed gate drivers. It serves as a direct replacement for legacy discrete buffer solutions, offering superior performance in terms of speed and reliability. The device is specifically engineered to drive N-channel power MOSFETs in demanding power conversion topologies where fast switching transitions are critical.

Telecom Replacement Considerations

The UCC2751DG4 is the lead-free RoHS-compliant version of this device. For new designs, consider upgrading to the UCC27511 or UCC27531 series, which offer updated features and active manufacturing status.
